I was looking at our NPS logs and aruba authentication logs (and dhcpd while I was at it...) and was shocked to see so many duplicate entries for all our iPhone users. Our dhcpd server often sees multiple requests, our NPS log is just full of them... We do not see any connectivity issues, or have any reported problems from the users, the devices all seem to be authenticating correctly. The major correlation I see is that almost all the devices that are showing this behavior are iphones.
Could this be because the nature of the device to be in a purse or pocket, and often hops on and off the network?
Just curious if anyone else is seeing this behaviour.

Iphones and Ipads are always on as users move around a campus they continually authenticate, laptops useally only auth when opened and turned on. In addition Ipads/Iphones do not support Opportunistic key caching, so they continually do a full re-auth 802.11r is suppose to resolve this if turned on... but also may cause some issues of its own.

that sucks... :)
It is so annoying - I can see 50-60 of these from one user over the course of 5 minutes if they are walking around campus. Is there anyway to slow this down. I like to have my radius logs, but man they are getting a bit crazy with all the iphone auths!

So is there anyway to help this issue? It seems the iPhones in particular do some agressive roaming of APs that seem to make this even more apparent...

Since you are not experiencing any performance, roaming or connectivity
issues, I wouldn't change anything.
Well I would not say I am not experiencing any issues - my radius accounting/logging would beg to differ :) My SQL radius logs are seeing around
2.5million entries a month... its kind of crazy...
I take that back - just checked my SQL log and just for today we have 234k log entries. So that would be almost 5million log entires a month!

You might want to contact Apple about that behavior...
